Madonna has paid tribute to her late brother Christopher Ciccone, who died at the age of 63 after a battle with cancer. In an emotional Instagram post, the singer described their bond as "hard to explain" and said dance was like "superglue" that held them together. The siblings, who were close during Madonna's early career, fell out in 2008 after Christopher released an autobiography about their relationship. However, they reconciled before his death. Ciccone was also an artist and interior designer, and directed music videos for other stars. Madonna's stepmother and older brother also died recently. The singer did not provide further details about her brother's death. Rest in peace, Christopher Ciccone. #Madonna #ChristopherCiccone #Cancer #Tribute #Family
